How to Soundproof a Car?
2 Answers
Simply install sealing strips on the car doors. Below is relevant information about automotive sealing strips: 1. Precautions: After installing sealing strips, the doors may not close properly, and the trunk may also become difficult to shut. If forced closed, some sealing strips may be squeezed out, affecting the vehicle's appearance. Additionally, sealing strips are typically black, making them very noticeable after installation. If this doesn't bother you, you can proceed with installation. Over time, exposure to wind, rain, and sunlight will cause the sealing strips to fall off, leaving adhesive marks that can look unsightly. 2. Overview: Automotive sealing strips serve to fill gaps between various body components, providing functions such as vibration reduction, waterproofing, dustproofing, sound insulation, and decoration, thereby enhancing driving comfort and protecting the vehicle body.
I used to often modify the sound insulation of my car myself. Let me explain the steps. First, prepare soundproofing cotton or damping mats, which can be easily purchased on Taobao or at auto parts stores—they're affordable and practical. The first step is to clean the interior surfaces, including the floor, door panels, and trunk, ensuring there’s no dust. Then, cut the materials and apply them, focusing on areas like under the hood and near the tires, where noise is the loudest. After installation, check the sealing to avoid gaps. The whole process takes less than an hour, and the effect is noticeable—engine noise is much quieter while driving, making the environment more enjoyable for listening to music. Regularly check if the materials have aged; they typically last about two years. This DIY approach is quite fun and also saves money on hiring a professional.
